Abstract: 1317689 Coating UTVECKLINGS AB TENET 20 Aug 1971 [31 Aug 1970 13 Aug 1971] 39221/71 Heading B2E [Also in Divisions C3 D1 and F4]  Water-wetted surfaces (e.g. metal, concrete, paper, plastics or wood) are dried by stripping water therefrom by applying a surfactant having a hydrophilic part and a hydrophobic part which parts are in hydrophilic-lipophilic balance so that the surfactant is soluble. A water-insoluble organic polar compound is preferably dissolved in the surfactant, and comprises a polar group (which bonds itself to the stripped surface) to render it water-repellent or corrosion-inhibiting and a hydrocarbon radical linked to the polar group. Groups of compounds suitable for use as the surfactant include alcohols, glycols, ketones, aldehydes, or organic sulphates or alkylaryl sulphonates which are liquid at room temperatures. Groups of substances suitable for use as the waterinsoluble organic polar compound include amines, long-chain fatty acids, phosphate esters, alkylated thiocarbamates, or alkylated benzoates. Further additives include substances for improving distribution (e.g. ketones such as acetone), substances for forming protective films (e.g. glycerin monooleate, liquid paraffin) and antioxidants (e.g. 2, 6-di-tert-butyl-4- methyl phenol). The surfactant is applied by spraying in fine drops, squirting as a liquid, brushing or dipping.

Abstract: 1,085,475. Magnetic matrix storage systems. SIEMENS A.G. Sept. 5, 1966 [Sept. 6, 1965], No. 39557/66. Heading H3B. The magnetic storage elements of a matrix are each associated with only two lines, a column line and a row line, connected to column and row selecting devices, and during read-out the voltage across a series arrangement of a column or row line and the corresponding selecting device is determined to indicate the information stored. If the row line is used for sensing the row half-select current is initiated before the column half-select current so that transients can decay. Alternatively the unwanted drive currents can be eliminated from the sense amplifier by providing an additional row of elements KZ in series with the selected row, Fig. 4. The drive current is derived from a constant current source Ik and is directed to the selected row by selecting device AZ. The drive current components of the voltages U z  and Uk are cancelled out by differential transformer U. In a modified arrangement (Fig. 5, not shown) the selected row and the additional row are connected in parallel to the drive amplifier. It is stated that a dummy row or column line may be provided instead of a complete row or column of storage elements.

Abstract: 1,212,786. Hollow fibres. MONSANTO CO. 29 Aug., 1968 [5 Sept., 1967], No. 41314/68. Heading B5B. A hollow synthetic fibre whose cross-section is depicted in the figure has a smooth surface which is essentially devoid of cracks and voids on the fibre surface and has a thick dense skin and large sealed voids within the interior of the fibre which are separated by at least one polymer bridge which connects the interior of the skin at least at two points within the interior structure of the fibre, the bridges being discontinuous along the length of the fibre. In the figure the uncollapsed voids are indicated by shaded areas. The fibre is made by extruding a synthetic fibre-forming polymer dissolved in a solvent into a coagulation bath preferably maintained at below - 10 C. and comprising carbon dioxide at or near the saturation level dissolved in a liquid medium which is a non-solvent for the synthetic polymer, a solvent for the polymer solvent and a solvent for carbon dioxide, so as to coagulate the extruded polymer solution by infusion of the medium containing CO 2  into the internal pore structure of the extruded polymer, immediately passing the coagulated filament into a heat-treating zone at temperatures between 50 to 100 C. The filaments can be stretched, washed and dried by conventional techniques. The fibre-forming polymer is preferably a polymer of acrylonitrile, and preferably contains at least 80% of acrylonitrile. The polymer may be a copolymer of from 80 to 98% acrylonitrile and from 2 to 20% of another monomer containing the > C=C < linkage and copolymerizable with acrylonitrile. A large number of suitable mono-olefinic monomers are given. The polymer may also be a ternary or higher interpolymer.

A one-way clutch for an auxiliary manual drive to the float of a liquid level gauging apparatus, in which a crank 52 may drive a sleeve 38 in one direction whilst the sleeve may rotate freely in both directions when not driven by the crank, comprises friction shoes 64 fast with a spring carrier 68 having a hub 74 engaged within a drag ring 76 provided with a projection 80 which, on clockwise rotation of the crank 52, engages a recess 82 in the housing 48 to hold the friction shoes 64 whilst the crank 52 rotates a tongue 60 relative to the shoes 64 and thus expands the latter into engagement with the sleeve 38. The crank 52 is connected to the tongue 60 through an overload slip coupling 53 which comprises resilient metal fingers 50a fast with the crank 52 and pressed by a spring 62 into engagement with a cylindrical block 58 fast with the tongue 60. During clockwise rotation of the crank 52 the carrier 68 and block 58 rotate together until the projection 80 engages recess 82 thereafter the tongue 60 expands the shoe 64 into engagement with the sleeve 38 whereupon the crank, block 58, shoes 64 and sleeves 38 rotate together whilst the carrier hub 74 slips within the drag ring 76. When the float reaches the limit of its movement and applies additional load to the sleeve 38 the coupling 53 slips during further clockwise rotation of the crank 52. Whilst the weight of the float loads the sleeve 38 the clutch remains engaged and anticlockwise rotation of the crank 54 permits the sleeve 38 to rotate in an anticlockwise direction. When the sleeve 38 is unloaded the spring carrier 68 retracts the shoes 65 from the sleeve 38 to permit free rotation of the sleeve.
